Q 781

Activating a scroll spell requires no material components or focus. (http://www.d20srd.org/srd/magicItems/scrolls.htm) However, there are several (https://www.d20srd.org/srd/spells/magicJar.htm) spells (https://www.d20srd.org/srd/spells/contingency.htm) which (https://www.d20srd.org/srd/spells/protectionFromSpells.htm) use (https://www.d20srd.org/srd/spells/secretChest.htm) their (https://www.d20srd.org/srd/spells/soulBind.htm) focus (https://www.d20srd.org/srd/spells/planeShift.htm) as an element in their effects. They're even on the treasure tables!

How do these spells function when you don't have their focus? (Are they tied to the focus the particular scroll was created with? Can you supply additional components for scrolls where this could change their effects?)

For context, activating scrolls:

Activating a scroll spell requires no material components or focus. (The creator of the scroll provided these when scribing the scroll.) Note that some spells are effective only when cast on an item or items (for example, Drawmij’s instant summons and snare). In such a case, the scroll user must provide the item when activating the spell. Activating a scroll spell is subject to disruption just as casting a normally prepared spell would be (see Cast a Spell, page 140 of the Player’s Handbook). Using a scroll is like casting a spell for purposes of arcane spell failure chance (such as from armor).

The "effective only when cast on an item" clause seems like it might be relevant, but both of the examples give target the objects in question, which even for secret chest is questionable (the replica is not a target). Perhaps a reasonable starting point for case-by-case rulings, but I don't really see how you could reasonably distinguish, say, plane shift from something like animate dead, or magic jar and contingency and protection from spells from shapechange.
